Question about 1994 Ford F150 Styleside Supercab
During warm or cold mornings when I start my truck the idle will oscillate from high to low rpm's. During our current cold temps in wisconsin it now cuts out until I start again. I'm guessing either a vacuum line or a mass air flow sensor or ??????
Any ideas or suggestions greatly appreciated.
I had this problem once on an econoline van and it was the plantum gasket but before you change this check all the vacuum lines and get a digital volt meter and test the voltages on the mass air flow sensor and if you have to change the plantum gasket auto zone can print you out a diagram stating all you have to remove to replace it
